Dear new2this,
Sounds like it might be a spirit of a deceased person. Because of the problem I have been afflicted by I've learned that there has been many cases of persons being possessed by or attached to such spirits in the hospitals, a place where many die. These spirits leave their physical bodies and because of fear or confusion not go to a spirit realm, but instead attach to another body. Perhaps, and I pray that this is the case, the previous responder is right and it is a spirit guide, but there are other possible explanations. It is well worth an investigation and if it is in fact a discorate spirit I suggest you deal with it as soon as possible, before it gets any more attached to your mother. The most comprehensive book I could find on this subject is
Spirit Releasement Therapy: A Technique Manual by William J. Baldwin
I seems to have a warse case though, having to deal with evil spirits, possibly demons. You are welcomed to read my story here:

I pray for your mother's healing.
Peace.
